What is the meaning of the parables of Jesus?

The parables of Jesus serve as illustrations of the profound truths concerning the Kingdom of God and are meant to penetrate the hearts of His listeners. In Matthew 13, Jesus explains to His disciples that the mysteries of the kingdom are given to them to understand, contrasting their understanding with that of others who do not perceive the truth. Thus, parables serve both to reveal and to conceal, depending on the receptiveness of the audience. Ultimately, these stories challenge self-righteousness and illustrate the necessity of recognizing one's own sinfulness and need for Christ.
